Description:The Roque Cinchado (Left of image) forms part of the Roques de García, a spectacular rock formation which are the remains of volcanic materials that were once located deep within the ancient Cañadas stratovolcano. The saw-tooth profile of the rock is due to the varying resistance to erosion of the different materials that make up the rocks. In the background is the impressive 3718 metre high Mount Teide stratovolcano, today crowned a small cone known as the Pilon de Azucar (Sugar Loaf), which is still residually active in the form of fumaroles of steam and sulphur at 86º C.
